Actually (nerd mode on), Dissidia gods summon not copies, but real characters to help them. The memories of the OG Dissidia and 012 events are sealed into each character who participated in them, and only awaken when the character returns to the Dissidia world. These memories are the reason why NT happens, as Cosmos doesn't want them to disappear and her desire to protect these memories takes the form of Materia. A little nod to that is a flavor text from the "Wind-up Kefka" minion, as Y'shtola thinks the doll is "eerily familiar". That is because she has sealed memories of fighting him before.
